The TL-4100S Residual Current Circuit Breaker is specifically designed for commercial and industrial electrical distribution systems requiring reliable earth-fault protection. This 4-pole RCCB monitors the current balance between live conductors and the neutral, instantly detecting any leakage to earth that could indicate a fault condition or potential safety hazard.
Built with electromechanical tripping technology, the TL-4100S operates independently of supply voltage, ensuring consistent protection even during voltage fluctuations or brownout conditions. The 300mA sensitivity rating makes it ideal for fire protection applications and main incomer protection in larger installations where higher leakage currents may be present under normal operating conditions.
With its robust 10kA breaking capacity and wide environmental tolerance, the TL-4100S provides dependable performance in demanding industrial environments. The compact design allows for efficient panel space utilization while maintaining full protection capabilities for three-phase plus neutral installations.
Tripping Characteristics:
The TL-4100S features instantaneous tripping with precise response times calibrated to international safety standards. At the rated sensitivity (1 × IΔn), the device trips within 0.2 seconds, while at 5 times the rated sensitivity (5 × IΔn), tripping occurs within 0.04 seconds, ensuring rapid disconnection during fault conditions.
Protection Technology:
The electromechanical tripping mechanism provides Type AC earth-leakage protection, suitable for detecting sinusoidal alternating residual currents. This technology ensures reliable operation without dependency on external power sources, maintaining protection integrity even during supply voltage variations.
Durability and Reliability:
Engineered for long service life, the TL-4100S offers 10,000 mechanical operation cycles and 4,000 electrical operation cycles under load conditions. The device operates reliably across a wide temperature range from -35°C to +70°C with humidity tolerance up to 95%, making it suitable for diverse environmental conditions.
Installation and Mounting:
The RCCB features standard DIN rail mounting for quick and secure installation in distribution boards and enclosures. With an IP20 degree of protection, the device is designed for indoor installation in controlled environments.
